Indeed, we've seen a few hacks that basically just enable FSGSBASE:

- https://github.com/occlum/enable_rdfsbase

And would very much like to get rid of them...

These are insecure and open root holes without the patches
used here.

It's sad that these hacks are being used alongside SGX on "secure"
systems.
